FIG. 2 is a flowchart of a communication control method for a UAVaccording to an embodiment of the present disclosure. As shown in FIG.2, the method of this embodiment may include:

S201: Transmitting a first information between the UAV and a payloadapparatus via a first communication link; and

S202: Transmitting a second information between the UAV and the payloadapparatus via a second communication link.

In this embodiment, the first information may be transmitted between theUAV and the payload apparatus via the first communication link, and inaddition, the second information may be transmitted between the UAV andthe payload apparatus via the second communication link. The firstcommunication link and the second communication link are differentlinks, and security of the first communication link may be higher thansecurity of the second communication link, and a bandwidth of the firstcommunication link may be than a bandwidth of the second communicationlink.

Since the security of the first communication link is higher than thesecurity the second communication link, the importance of the firstinformation may be higher than the importance of the second information.Accordingly, the information transmitted between the UAV and the payloadapparatus can be transmitted based on the different importance viadifferent communication links (e.g., the above-mentioned firstcommunication link or the above-mentioned second communication link).Since the bandwidth of the first communication link is smaller than thebandwidth of the second communication link, a data volume of the firstinformation can be smaller than a data volume of the second information,so the information transmitted between the UAV and the payload apparatuscan be based on the different data volumes via different communicationlinks (e.g., the above-mentioned first communication link or theabove-mentioned second communication link).

The embodiment does not limit the execution sequence between S201 andS202.

In this embodiment, the UAV communicates with the payload apparatus viatwo communication links. Since the security and the bandwidth of the twocommunication links are different, accordingly, the information matchingthe communication links can be communicated via different communicationlinks. Accordingly, the UAV communicates a part of the information withthe payload apparatus via the first communication link, and communicatesanother part of the information with the payload apparatus via thesecond communication link, thereby improving the success rate of theinformation transmission between the UAV and the payload apparatus.

In some embodiments, the aforementioned transmission of the firstinformation between the UAV and the payload apparatus via the firstcommunication link may include: the UAV sends the first information tothe payload apparatus via the first communication link, and/or, the UAVreceives the first information from the payload apparatus via the firstcommunication link. In this embodiment, the information communicatedbetween the UAV and the payload apparatus via the first communicationlink is collectively referred to as the first information. In practicalapplications, the information that the UAV communicates to the payloadapparatus via the first communication link may be different from theinformation the UAV receives from the payload apparatus via the firstcommunication link. For example, the first information communicated fromthe UAV to the payload apparatus via the first communication link mayinclude a control command configured to control the payload apparatus.The first information received by the UAV from the payload apparatus viathe first communication link may include alarm information.

The following describes an example in which the UAV communicates thefirst information to the payload apparatus via the first communicationlink. The remote-control device (for example, the control device 140shown in FIG. 1) communicates the first information to the UAV. Theremote-control device transmits the first information to the UAV via acommunication link with the UAV (hereinafter referred to as a thirdcommunication link). The remote-control device may, for example,transmit the first information to the UAV according to a user'soperation. After receiving the first information transmitted by theremote-control device via the third communication link, the UAVdetermines whether the first information indicates to be communicatedwith the payload apparatus. When the first information indicates to becommunicated with the payload apparatus, the UAV communicates the firstinformation with the payload apparatus via the first communication link.The first information may include, for example, a control commandconfigured to control the payload apparatus. When the first informationindicates to be transmitted to the UAV, the UAV sends the firstinformation to the flight controller of the UAV. The first informationincludes a field for identifying a receiving end (i.e., a transmissiondestination) of the first information. If the field identifies that thereceiving end of the first information is a UAV, it means that the firstinformation indicates to be transmitted to the UAV. If the fieldidentifies that the receiving end of the first information is a payloadapparatus, it indicates that the first information indicates to betransmitted to the payload apparatus. Therefore, in this embodiment, theremote-control device can implement the control of the payloadapparatus.

The following describes an example in which the UAV receives the firstinformation from the payload apparatus via the first communication link.The payload apparatus transmits the first information to the UAV. TheUAV receives the first information transmitted by the payload apparatusvia the first communication link, and then the UAV transmits the firstinformation received from the payload apparatus to the remote-controldevice. The UAV may transmit the first information to the remote-controldevice via the communication link with the remote-control device(hereinafter referred to as the third communication link). Optionally,the first information received by the UAV from the payload apparatus viathe first communication link may include alarm information. For example,the alarm information may be an alarm information that the temperatureof the payload apparatus is too high. After receiving the alarminformation via the third communication link, the remote-control devicemay, for example, output the alarm information via an output device,such as displaying the alarm information via a display device.

In some embodiments, transmitting the second information between the UAVand the payload apparatus via the second communication link includes:receiving the second information by the UAV from the payload apparatusvia the second communication link. In this embodiment, the payloadapparatus transmits the second information to the UAV. The secondinformation may include sensor data, e.g., image data, environmentaldetection parameters, etc. The UAV receives the second informationtransmitted by the load via the second communication link, and thentransmits the second information to the remote-control device. The UAVcan send the second information via a communication link with theremote-control device (referred to as a fourth communication link).After receiving the second information via the fourth communicationlink, the remote-control device may, for example, output the secondinformation via an output device, such as displaying the secondinformation via the display device.

In some embodiments, the UAV and the remote-control device cancommunicate wirelessly. Therefore, before the UAV communicates with theremote-control device, the UAV may establish a communication link withthe remote-control device via an antenna. The UAV may be connected tothe remote-control device via a first antenna to establish the thirdcommunication link, and may also be connected to the remote-controldevice via a second antenna to establish the fourth communication link.

In some embodiments, the third communication link and the fourthcommunication link may be the same communication link. In this case, theabove-mentioned first antenna and the second antenna are the sameantenna; that is, the UAV is connected to the remote-control device viathe antenna to establish the communication link, and the antenna has atransceiver function.

In some embodiments, the third communication link and the fourthcommunication link may be different communication links.Correspondingly, the aforementioned first antenna and second antenna aredifferent antennas. Optionally, security of the third communication linkmay be higher than security of the fourth communication link, and abandwidth of the third communication link may be lower than a bandwidthof the fourth communication link. The third communication linkcorresponds to the first communication link; the UAV transmits theinformation received from the first communication link to theremote-control device via the third communication link, and the UAVtransmits the information received from the third communication link tothe payload apparatus via the first communication link. The fourthcommunication link corresponds to the second communication link, and theUAV transmits the information received from the second communicationlink to the remote-control device via the fourth communication link.

In some embodiments, the third communication link may be a commandchannel (e.g., a channel assigned to transmit commands and/or non-imagedata), and the fourth communication link may be an image transmissionchannel (e.g., a channel assigned to transmit image data, environmentaldata, sensor data, and/or non-command data).

In some embodiments, the first communication link may be a commandchannel, and the second communication link may be an image transmissionchannel.

In some embodiments, since the UAV and the payload apparatus communicateinformation via two communication links, the UAV can be connected to thepayload apparatus via two communication interfaces, and the twocommunication interfaces may be a first communication interface and asecond communication interface.

In some embodiments, the UAV and the payload apparatus can be directlyconnected. For example, as shown in FIG. 3, the UAV can identifycommunication protocol of the payload apparatus, and the payloadapparatus can also identify the communication protocol of the UAV. Inthis embodiment, before the UAV communicates with the payload apparatus,the UAV may be connected to the payload apparatus via the firstcommunication interface to establish the first communication link, andthe UAV may also be connected to the payload apparatus via the secondcommunication interface to establish the second communication link.

In some embodiments, the UAV and the payload apparatus need to beconnected via an adaptor device, for example, as shown in FIG. 4. Thatis, the adaptor device is connected between the UAV and the payloadapparatus, and the payload apparatus cannot recognize the communicationprotocol of the UAV, but the adaptor device can identify thecommunication protocol of the payload apparatus and the communicationprotocol of the UAV. In this embodiment, before communicating with thepayload apparatus, the UAV can be connected to the adaptor device viathe first communication interface to establish the first communicationlink and can be connected to the transfer device via the secondcommunication interface to establish the second communication link. Inaddition, the adaptor device may include a third communication interfaceand a fourth communication interface. The adaptor device may beconnected to the payload apparatus via the third communicationinterface, and the adaptor device may be further connected to thepayload apparatus via the fourth communication interface. The thirdcommunication interface and the fourth communication interface may notbe the same interface. As such, two communication links can also beestablished between the adaptor device and the payload apparatus, onecommunication link corresponds to the third communication interface, andthe other communication link corresponds to the fourth communicationinterface.

In the process of information transmission, the UAV transmits the firstinformation to the adaptor device via the first communication link; theadaptor device then transmits the first information received via thefirst communication link to the payload apparatus via the thirdcommunication interface. The payload apparatus can transmit the firstinformation to the adaptor device via a communication link correspondingto the third communication interface. After receiving the firstinformation via the third communication interface, the adaptor devicemay forward the first information to the UAV via the first communicationlink. The payload apparatus may also transmit the second information tothe adaptor device via a communication link corresponding to the fourthcommunication interface. After receiving the second information via thefourth communication interface, the adaptor device may forward thesecond information to the UAV via the second communication link.

It should be noted that FIG. 3 and FIG. 4 are shown as examples in whichthe communication module of the UAV communicates with the payloadapparatus and the remote-control device, respectively.

In some embodiments, if the communication protocol of the payloadapparatus is the first communication protocol, the communicationprotocol of the UAV can be the second communication protocol, and thefirst communication protocol is different from the second communicationprotocol.

The adaptor device can receive the first information based on the firstcommunication protocol that is transmitted by the payload apparatus viathe third communication interface, and then convert the firstinformation based on the first communication protocol into a firstinformation based on the second communication protocol, and thentransmits the first information based on the second communicationprotocol to the UAV via the first communication link.

The adaptor device can receive the first information based on the secondcommunication protocol that is transmitted by the UAV via the secondcommunication link, and then convert the first information based on thesecond communication protocol into the first information based on thefirst communication protocol, and then transmits the first informationbased on the first communication protocol to the payload apparatus viathe third communication interface.

The adaptor device can receive a second information based on the firstcommunication protocol that is transmitted by the payload apparatus viathe fourth communication interface, and then convert the secondinformation based on the first communication protocol into a secondinformation based on the second communication protocol, and thentransmits the second information based on the second communicationprotocol to the UAV via the second communication link.

In some embodiments, the aforementioned third communication interfacemay be a controller area network (CAN) interface, or a universalasynchronous receiver/transmitter (UART) interface, or a recommendedstandard (RS)-232 interface, or RS-485 interface, or RS-422 interface,which is not limited by the embodiment.
